Sometimes when I visit a website, it will be redirected to another site. I think it is a good way to promote my site (e.g. when a user visits a site, he will be redirected to my site). Where can I buy such redirect ad?
This is literally the worst way to promote your site. Nobody fucking likes redirects and everyone closes out. Plus, you'd absolutely make sure your site is permanently banned from every quality ad network in the world because it was the target for redirects. Market your site legitimately, not through weird shit.
